HÀ NỘI – The water quality of lakes, rivers, streams and canals in Việt Nam is seriously degrading. Water in urban areas and industrial zones poses risks to human and aquatic animals.

Rivers such as Tô Lịch, Sét and Kim Ngưu in Hà Nội have become sections of the city’s waste water drainage system.

The information was revealed yesterday in a water pollution report conducted by the Coalition for Clean Water and the Centre for Environment and Community Research (CECR) under the Việt Nam Union of Science and Technology Organisations.

Calculations have shown that 10 per cent of all plastic produced around the world ultimately ends up in the oceans. As a result, a large majority of global marine debris is in fact plastic waste. Human production of plastics is a well-known environmental concern, but few studies have studied the effects of tiny plastic particles, known as nanoplastic particles.

"Our study is the first to show that nanosized plastic particles can accumulate in fish brains," says Tommy Cedervall, a chemistry researcher at Lund University.

Exclusive: Tests show billions of people globally are drinking water contaminated by plastic particles, with 83% of samples found to be polluted

Microplastic contamination has been found in tap water in countries around the world, leading to calls from scientists for urgent research on the implications for health.

Scores of tap water samples from more than a dozen nations were analysed by scientists for an investigation by Orb Media, who shared the findings with the Guardian. Overall, 83% of the samples were contaminated with plastic fibres.

BWT, Europe's leading water technology company, has given Sahara Force India a brand-new look. In the 2017 Formula 1 season their VJM10 will be competing in the colours of pink, magenta and silver, clearly signalling a long-term relationship between BWT, the Austrian-headquartered water brand, and the Formula 1 team, Sahara Force India. The new colours were seen for the first time at the opening race of the season, the Australian Grand Prix, in Melbourne.

A check on the quality of tap water in Ho Chi Minh City by the Ministry of Health showed that the content of chlorine, widely used to purify water as a disinfectant and bleaching agent, fails to meet required standards.

Chlorine concentration was found exceeding the maximum level in areas near the reservoirs of Saigon Water Supply Corporation (SAWACO) and being below the minimum rate in other areas far from the lakes, according to the results of the check.
